First discovery of its type in nearly 100 years
Scientists in Brazil say they have identified a new species of river dolphin, the first to be discovered in nearly 100 years.
River dolphins are among the most endangered mammals in the world.
The new species was found in the Araguaia River Basin in Brazil.
Researchers from the Federal University of Amazonas (UFAM) and the National Research Institute of the Amazon (INPA) in Brazil and say the species separated from other Amazonian dolphins more than two million years ago.
"This discovery highlights the immensity of the deficit in our knowledge of Neotrpical biodiversity, as well as vulnerability of biodiversity to anthropogenic actions in an increasingly threatened landscape," wrote lead author Tomas Hrbek in the journal Plos One .
The research paper added that three of the four existing species of river dolphin are listed by the International Union for Conservation of Nature's (IUCN) red list as under threat.
